Application filed September 13, 1910. Serial No. 581,325.

To all whom it may concern:

Be it known that we, WARREN I-I. MAPLE and Orro F. TURNER, citizens ofthe United States, residing at Pendleton, in the county of Umat-illa andState of Oregon, have iiivented a new and useful Improvement inl'uitomatic Cartridge-Registers, of which the following is aspecification.

This invention relates to certain new and useful improvements incartridge registers for magazine fire arms, the object being to providea register which is so constructed that the same can be readilyconnected to any of the magazine tubes, used in magazine rifles of allkinds, whereby the number of cartridges within the magazine can beascertained at any time.

A further object of our invention is to provide a cartridge register orindicator which is so constructed that the same can be used to indicatenumber of cartridges within the magazine of long or short cartridges, bysimply shifting the indicating plate.

A further object of our invention is to provide a register or indicatorwhich is exceedingly cheap and simple in construction, and one in whichthe parts are so arranged and connected, that all danger of the samebecoming disarranged when in use is prevented.

A still further object of our invention is to provide a register orindicator which can be secured in position on an ordinary magazine tubeby simply removing the head of the same and inserting our improvedregister therein and securing the same by a pin.

With these and other objects'in view, our invention consists in" thenovel features of construction, combination and arrangement of parts,hereinafter fully described and pointed out in the claims.

In the drawings forming a part of this specification: Figure 1 is a sideelevation of a rifle showing the application of our improved register.Fig. 2 is a longitudinal section through the magazine tube. Fig. 3 is adetail longitudinal section through the same. Fig. 4 is a transversesection through the head. Fig. 5 is a detail plan view of the indicatingtape.

In carrying out our improved invent-ion we employ a magazine tube A ofthe ordinary construction which is provided with a sliding plunger Bactuated by a coiled spring C which normally holds the plunger projectedpartially out of one end of the tube for forcing the cartridges into thereceiver of the magazine andthe other end of the tube is left openedtoreceive our improved invention, the above description be ing given sothat the operation of our improved invention when applied to themagazine tube can be readily understood.

Our invention comprises a head D having a rounded end portion D and astem D adapted to fit within the end of the magazine tube A and besecured by a pin E passing transversely through the same, said stemhaving a strip F extending centrally therefrom, which is adapted toextend within the coiled spring C, for the purpose hereinafter fullydescribed. Arranged over the head I) is a casing G provided with amilled portion. G and a sight opening H covered by glass H, which isembedded therein flush with the outer face, which prevents water anddirt from getting within the casing, and said casing is substantiallythe same shape as the head, and is spaced therefrom, as clearly shown.

Secured in the plunger B, is a rod I which extends within the coiledspring and has an indicating tape J, connected to its free end, whichextends alongside of the strip F, and is adapted to pass through one ofthe slots K formed in the stem 1) which communicates with the interiorof the casing. The slots K extend longitudinally through the stem D toeach side of the strip F, and the portions of the strips are cut away,and the end portions bent outwardly as shown at K, for guiding the metalindicating tape J through the slots, and when the spring is compressed,the tape will pass around the head within the casing, under the sightopening and outthrough the opposite slot, the strip F holding the tapeapart, so that the same will slide freely.

The indicating tape J is provided w1th designating numerals from O to15, upon one side for indicating the number of cartridges within themagazine tube, for instance 22 longs and upon the other side designatingnumerals for indicating the number of 22 shorts within the magazinetube, and it will be seen by this construction it is only necessary toremove the end of the tape from the slot, and turn the same over, inorder to change the register, so that the same Wlll indicate the shortercartridge.

Having thus fully described -our invention, What We claim as new anddesire to secure by Letters Patent is 1. The combination with a magazinetube having a spring actuated plunger, of a head provided with a stemarranged Within the end of said tube, said stem being provided withslots, a casing arranged oversaid head and spaced therefrom, said casingbeing provided with a sight opening, and an indicating tape connected tosaid plunger adapted to pass through said slots around said head Withinsaid casin 2. An indicator for magazine tubes comprising a head adaptedto be secured Within the end of a magazine tube, a casing arranged oversaid head provided With a sight opening, and an indicating tape passingthrough said casing over said head having one of its ends connected tothe plunger of the magazine tube.

3. The combination with a magazine tube havinga spring actuated plunger,of a rod connected to said plunger, an indicating tape connected to saidrod,v a head arranged within the end of said tube, a casing arrangedoversaid head provided with a sight opening, said head being providedwith a passage to receive the indicating tape.

l. The combination with a magazine tube having a spring actuatedplunger, of a head provided with a stem arranged Within said tube, astrip secured centrally Within the end of said stem, a casing arrangedover said head and spaced therefrom forming a passage, a sight openingcommunicating With said passage, said stem being provided With slotscommunicating With the passage of the head and a tape carried by theplunger of said tube having designating numerals upon opposite sidesadapted to pass through said slots and passage under said sight opening.
